Preheat the oven to 160ºC/320ºF; line two large baking sheets with baking paper.

To make the filling, place the butter and sugar in the bowl of an electric mixer and beat for 6-8 minutes or until pale and creamy. Strain the passion fruit pulp through a sieve to remove the seeds. Add to the butter mixture and beat for further 3-4 minutes or until smooth. Set aside.
Make the cookies: place the butter, sugar and lemon zest in the bowl of an electric mixer and beat for 6-8 minutes or until pale and creamy. Add the flour, corn flour and passion fruit pulp and mix in slow speed until combined. Roll 1 rounded teaspoon of the mixture into balls with damp hands and place on prepared sheets – if the mixture gets a little sticky, refrigerate it for 15-20 minutes. Press each cookie with a damp fork to flatten. Bake for 12-15 minutes or until light golden. Allow to cool on sheets.
Sandwich the cookies together with the passion fruit filling to serve.

* I was pretty generous filling the cookies and still got loads of filling left. I believe half the recipe would be enough.

AH HA HA HA! I'VE WATCHED THAT MOVIE PROBABLY SEVEN TIMES TOOOOO!!! Sorry for the loudness, heh heh :) I love that movie, all the way down to the cheesy way Streisand covers the mirror with her damn towel during her wedding night! Sooooo 1950's! Also my favorite of the stupid parts? When the young college students are licking their lips over Streisand (post-makeover) and Bridges! What gives those scenes so much flavor is that Streisand directed the movie! But yes, I love it so much :)

Ahem. Anyway, I love the cookies too- they look so tender, and twice as irresistible with the cream filling :)

I love the name of the cookies!I discovered passionfruit a few years ago. It has such an unusual taste. Friends have a passionfruit tree and now we get the fruit in large amounts. Nice because it's expensive here. Is it expensive where you are?

Erin, you are right - these are similar to melting moments!I'm glad you like them, tks!

Food Librarian, I love passion fruit, too!

Pete, I did get the recipe from an Aussie magazine! :DAustralia is a country I would love to go to.

May, I'd love to hear your opinion about them!

Ilingc, I absolutely love Donna! Her recipes work every time and never disappoint.Thank you, sweetie!

Sunita, yours are adorable and I love how you shaped them. ;)

Alexa, they melt in your mouth due to the addition of corn starch.

Cathy, thank you, darling.

KJ, Donna Hay introduced these to me. :D

Susan, isn't Lauren Bacall amazing on the movie? Thank you!

Mark, as cheesy as some moments are - and I recognize that - I love the movie! Lauren Bacall is amazing, and I do love Jeff Bridges, too - he is such a great actor but never get the credit he deserves, in my opinion.Oh, and Ms Streisand wrote it and was involved in the soundtrack, too. :)

Natalie, it's a great movie, but not very serious. :)I hope you like it!

Maya, she is amazing, I'm a huge fan!

Joey, I knew you would remember!! :D

Mari, they are not expensive here - a tropical fruit in a tropical country - and I love them. The smell is quite something, too!

These are ever so pretty Patricia...never heard of yoyo cookie & can't get passion fruit here...but have fallen in love with these lovely creatures. And now if Manggy doesn't stop yelling about Streisand, I'm going to become a cookie monster!! LOL!!
